ABB 1SBL281024R5110 Contactors

Description

• The ABB 1SBL281024R5110 UA30..RA 3-pole contactors for capacitor switching are a reliable and essential component for installations where peak currents far exceed 100 times the nominal rms current. These contactors are designed to handle the demanding task of capacitor switching and come complete with damping resistors, eliminating the need for additional inductances.

• One of the key features of these contactors is their ability to safely handle high currents while ensuring the longevity of your electrical system. The capacitors must be discharged to a maximum residual voltage of less than 50 V before being re-energized when the contactors are in the closed position. This safety measure prevents unwanted electrical surges and ensures the protection of your equipment.
